Koshi Forest Wind Chime • 440Hz • Earth Symphony

Deep, nuanced and contemplative, the Koshi Forest Chime is part of the new Koshi Earth Symphony collection, inspired by the mystery and living presence of great forests.

Handcrafted and individually hand-tuned at the foot of the French Pyrenees, Forest contains twelve steel rods arranged around the notes C# • F# • F# • G# • G# • A • A • C# • F# • G# • A • C#, creating an F# minor harmonic structure.

Each rod is tuned by hand with reference to 440Hz, allowing the notes to settle into a deep and coherent harmonic ensemble.

Four of the twelve rods are doubled at identical frequencies, acting as sympathetic resonators. These repeated pitches help extend the resonance and give Forest a denser, more immersive sonic texture.

The result is a rich, mysterious and contemplative sound in which the notes emerge, overlap and gradually fade into silence.

Forest can be played by hand during meditation, yoga and sound practice, combined with singing bowls and gongs, or suspended in a sheltered position where movement of the air allows the chime to play naturally.

Within the Earth Symphony collection, Forest may symbolically evoke mystery, stillness, contemplation, introspection and the layered life of woodland spaces.

Forest is one of four complementary Koshi Earth Symphony melodies:

Mountain • Forest • River • Ocean

The classic Koshi 4 Elements collection remains a separate range featuring Terra, Aqua, Aria and Ignis with 8 rods and an adjusted 432Hz reference.

Forest • Earth Symphony

Forest is one of four melodies within the Koshi Earth Symphony collection.

Where the classic Koshi 4 Elements range takes inspiration from Earth, Water, Air and Fire, Earth Symphony turns toward four great natural landscapes:

Mountain • Forest • River • Ocean

Forest explores the mystery, depth and layered stillness of woodland.

Its musical character is inspired by the forest as a living space and may evoke hidden voices, silence, contemplation and introspection.

The twelve rods create a dense but coherent field of sound, with notes appearing and disappearing within the wider resonance.

The Forest association is symbolic and musical rather than a claim of fixed energetic effects.

Notes & Harmonic Structure

Forest is built around the notes:

C# • F# • F# • G# • G# • A • A • C# • F# • G# • A • C#

These notes form an F# minor harmonic structure.

Each of the twelve rods is individually tuned by hand.

Four pitches are doubled at identical frequencies, creating what Koshi describes as sympathetic resonators.

These repeated rods reinforce selected frequencies and contribute to the instrument's deeper resonance and more immersive sonic texture.

Rather than functioning as twelve isolated tones, the rods work together as one harmonic ensemble.

Twelve Hand-Tuned Steel Rods

Forest contains twelve steel rods.

This gives Earth Symphony a broader sonic architecture than the classic 8-rod Koshi 4 Elements collection.

Each rod is individually tuned before being soldered with silver onto a metal base.

The additional rods create more harmonic relationships within the instrument and allow the sound to develop with greater density and sustain.

The effect is not simply greater volume.

It is a richer field of interacting fundamentals, repeated frequencies and overtones.

Sympathetic Resonators

One of the defining technical features of Earth Symphony is the use of doubled rods.

Four rods are tuned to frequencies already present elsewhere in the instrument.

These doubled pitches act as sympathetic resonators.

When related notes sound, the repeated frequencies help reinforce the wider harmonic structure.

This contributes to Forest's depth, sustain and layered resonance.

440Hz Tuning Reference

Koshi Forest is tuned with reference to 440Hz.

This does not mean that every rod produces a single 440Hz tone.

Each rod has its own pitch within the F# minor structure.

The 440Hz reference forms part of the wider tuning system used to position those pitches accurately within the harmonic ensemble.

Each rod is tuned individually until it sits correctly within the complete instrument.

How to Play the Koshi Forest

Hold the chime by its cord and let the wooden body hang freely.

Turn it gently with a small movement of the wrist.

The central clapper then begins to strike the rods, bringing out a cascade of broad and deep notes.

The broader the movement, the more rods are set in motion.

For more isolated tones, swing the chime gently in a pendulum motion.

There is no need to shake the instrument strongly.

Gentle movement allows the longer resonance and interaction between the rods to develop more naturally.

Use as a Wind Bell

Forest can also be suspended so that a gentle breeze moves the internal clapper.

This allows it to function as a tuned wind bell.

Because the movement of the air determines which rods sound and in what order, the resulting musical patterns remain changing and unpredictable.

For longevity, indoor use or a dry, sheltered outdoor position is preferable to permanent exposure.

Avoid prolonged rain, damp, frost and severe weather.

Koshi Forest Meditation Chime

Forest works beautifully as a meditation chime where a deeper, more introspective and contemplative sound is preferred.

A gentle movement at the beginning of a practice can mark the transition into stillness, while another at the end can signal the return to ordinary awareness.

Its longer resonance allows individual notes to appear, overlap and gradually fade into silence.

This makes Forest particularly suited to listening practices centred on stillness, attention and reflection.

During Meditation

Forest can be used at the beginning or end of meditation, during breathwork, between stages of a practice or simply as a focus for attentive listening.

Its deeper character gives the sound room to unfold without needing constant movement.

There is no required sequence.

Yoga Chime

Forest also suits yoga and movement practice.

Its light weight makes it easy for a teacher or practitioner to move through a space, while its sustained resonance can mark transitions without sounding abrupt.

It can work especially well during restorative yoga, savasana, breathwork, slow transitions and quiet mindfulness periods.

Its deeper musical character may suit moments where a more inward or reflective atmosphere is wanted.

Sound Bath & Sound Practice

Within sound practice, Forest can sit naturally alongside singing bowls, gongs and other harmonic instruments.

Its twelve-rod structure creates a dense but coherent tonal layer that can add depth without overpowering the wider soundscape.

Because the chime is light enough to move easily, a practitioner can also allow the sound to circulate through the room.

Forest can be used to introduce a session, mark transitions, deepen a quieter section, add sustained harmonic texture or guide attention back toward silence.

References to sound baths or sound therapy describe the contexts in which the instrument may be used and do not imply guaranteed therapeutic outcomes.

Oak Resonance Chamber

Forest uses an oak wood resonance chamber.

The wooden chamber surrounds the twelve steel rods and helps amplify and sustain their vibration.

This allows the notes and harmonics to linger and interact rather than disappearing immediately after the first strike.

The combination of oak and steel contributes to Forest's long, clear and warm resonance.

Brass & Coconut Shell Clapper

Forest uses a brass and coconut shell clapper.

As the chime moves, the clapper strikes different rods naturally, creating changing combinations of notes and harmonics.

The manufacturer describes the Earth Symphony construction as plastic-free.

Sound Character

Forest has a deep and contemplative sound.

Its F# minor structure gives the melody a more inward and mysterious musical character.

The twelve rods create a dense sonic texture in which individual notes emerge, respond to one another and gradually dissolve.

The doubled sympathetic resonators reinforce selected frequencies and contribute to the feeling of depth.

This makes Forest especially suited to situations where you want a sound that feels layered, reflective and slightly mysterious.

Forest Symbolism

Forest takes its inspiration from great forests as living, layered spaces.

Its musical character may evoke:

  • mystery
  • contemplation
  • introspection
  • silence
  • depth
  • hidden movement
  • living natural presence

These associations describe the inspiration behind the melody rather than guaranteed energetic properties of the instrument.

You can choose Forest entirely because you enjoy its sound.

Designed to Play with Mountain, River & Ocean

The four Koshi Earth Symphony melodies were designed to work alone or in dialogue with one another.

Mountain • Forest • River • Ocean

Their chords remain musically coherent when different combinations are played together.

Forest retains its own deeper, more mysterious identity while still finding its place within the wider Earth Symphony ensemble.

Mountain provides a broad and grounded presence, while River and Ocean bring their own contrasting sound worlds.

You do not need all four to enjoy Earth Symphony, but the collection has been designed so that its melodies can respond freely to one another.

Koshi Earth Symphony & 4 Elements

Koshi now has two distinct musical collections.

Earth Symphony contains Mountain, Forest, River and Ocean.

Each Earth Symphony chime uses 12 steel rods, 4 doubled sympathetic resonators, a 440Hz tuning reference, a fine-wood resonance chamber, a brass and coconut shell clapper, and plastic-free construction as supplied.

The classic Koshi 4 Elements collection contains Terra, Aqua, Aria and Ignis.

Those chimes use 8 rods, treated bamboo resonance chambers and an adjusted 432Hz reference.

The two collections are separate musical systems.

Which Koshi Collection Should I Choose?

Choose Earth Symphony if you want a broader, more immersive Koshi sound with twelve rods and a 440Hz reference.

Choose the classic 4 Elements range if you prefer the original eight-rod Koshi format with Terra, Aqua, Aria and Ignis and an adjusted 432Hz reference.

Within Earth Symphony, Forest is especially suited to someone drawn to a deep, nuanced, mysterious and contemplative musical character.
